I have a John Deere 310C Backhoe that recently started lacking power. I was running it one day and it started to lose power, then would not rev up, gain RPMs. It seems to be running around 1200-1500 RPM but no more with the throttle open. I have replaced the fuel filter, oil is good, diesel is 1 month old. It will drive slow in forward and reverse, the hydraulics work well, but it just lacks power as I believe the RPMs are low. Throttle linkage is good. The throttle open to the screws still doesn't get the RPMs above 1500.
I suspect a fuel delivery problem or injection pump problem. injection pump RE-21773. I will apologize I am an amateur mechanic, but would appreciate help and direction in solving this matter.

! Some simple checks before we go to pressure checks. I would check your fuel tank vent (part of the fuel cap). If the the fitting in the top of your injection pump (as Tyler mentioned above) does not resolve your issue and the vent is clear I would check the suction screen in your tank. It is attached to the fitting that is screwed into the bottom of the tank.
